Combining functional and structural approaches for switched-current circuit testing

This paper aims at defining an efficient test strategy for switched-current circuit testing. Taking into account the specificity of these circuits, we propose an original structural test technique as an alternative to traditi onally-used Functional verification. This technique is validated both at th e cell and block levels. Test results demonstrate that a high fault coverag e can be achieved with a low cost test procedure. A mixed strategy combinin g benefits of functional and structural approaches is derived.
